Location: Akwa Ibom State, NigeriaStatus: Completed 2011

Elekahia Bridge

Location: City of Port Harcourt, NigeriaStatus: Completed 2011

Project Description

The Elekahia bridge is a new 32m long railway bridge above a main road in the city of Port Harcourt, Nigeria.

The initial plan was to replace an existing bridge, with a new one. However, as site works in this location would cause a significant disruption to the bottle necked traffic, it was decided to relocate the entire intersection 100m eastwards, thus reducing the impact.

ConstructionTo accommodate the existing lay of the land, the bridge was designed utilising top-down construction, where the bridge was built from deck level, downwards.Piled foundations were drilled from deck level and the deck was then cast directly onto the ground.

After casting the post-tensioning the deck, the soil beneath it was excavated, down to the proposed level of the new road.

Benue River Bridge

Location: Kogy State-Nasarawa State, NigeriaStatus: Completed 2011

Project DescriptionThe Benue River Bridge is located at the border of the Kogi and Nassarawa states in Nigeria, creating a road link between Bagana and Guto. The project includes the design and construction of two parallel bridges, each 1270m long and 11m wide.

The bridges are a series of 50m long main spans and 35m long end spans and crosses the Benue River perpendicular to the flow.

ConstructionThe bridge superstructure is made of precast segmental concrete, constructed by the span-by-span method, using an under-slung assembly machine. The precast segments were produced by the long-line method at a factory nearby.

Each bridge superstructure is made of four continuous girders, separated by expansion joints. The substructure is made of reinforced concrete, oval-type mid-piers, which were designed to support the under slung assembly machine.The bridge foundations and substructure are cast in-situ concrete drilled piles.

Elelenwo Bridge

Location: City of Port Harcourt, NigeriaStatus: Completed 2017
